Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to an air fryer. Background Technology

[0002] An air fryer is a kitchen appliance that uses a high-temperature, high-speed airflow to circulate and heat food. It is popular because it achieves a cooking effect similar to deep-frying while using less oil. Its basic structure typically includes a pot body, a frying basket, and a heating element located at the top of the pot body. The heating element generally includes heating elements, a fan, and fan blades. During operation, the fan drives the airflow, which is heated by the heating elements and then blown onto the food in the frying basket to cook it. However, existing air fryers of this type have some significant drawbacks. First, during cooking, food produces volatile oils and moisture. These oil droplets and steam are carried upwards by the high-speed airflow, and because the heating element is unobstructed, the oil droplets directly adhere to the high-temperature heating element and the fan blades located above it. The heating element is often a complex spiral shape (like a mosquito coil), making cleaning extremely inconvenient; and the fan blades are obstructed by the heating element, making cleaning impossible without disassembling the product. Long-term accumulation of grease not only produces unpleasant odors and mold, affecting food safety, but may also carbonize on the heating element, affecting heating efficiency and even posing safety hazards.

[0003] Secondly, the existing air duct design is often rather crude, lacking effective guidance and constraint of the airflow path. This results in some airflow entering the cooking cavity without sufficient contact and heat exchange with the heating element. This uneven airflow distribution and low heat exchange efficiency cause uneven heat distribution within the cooking cavity, leading to uneven heating of the food, which in turn affects the cooking effect, resulting in slow heating speed and increased energy consumption. Utility Model Content

[0004] The purpose of this invention is to disclose an air fryer that systematically solves the problems of grease contamination and air duct efficiency by using a layered isolation design for the heating components and a directional airflow design.

[0005] To achieve the above objectives, this utility model discloses an air fryer, comprising: a main body assembly, the main body assembly including an outer shell frame and a heat-insulating basket installed within the outer shell frame; a frying basket assembly, the frying basket assembly being detachably installed within the heat-insulating basket; and a heating assembly, the heating assembly being assembled above the heat-insulating basket, the heating assembly including, from bottom to top, a lower cover of the heating chamber, a heating tube, an air guide plate, a heat insulation plate, and a fan; wherein, the lower cover of the heating chamber is provided with an air outlet communicating with the interior of the frying basket assembly, and the air guide plate is provided with multiple air guide holes corresponding to the heating tube, so that the air from the fan flows through the air guide holes, passes through the heating tube, and then enters the frying basket assembly through the air outlet.

[0006] By adopting the above scheme, the heating chamber lower cover, heating element, air guide plate, heat insulation plate, and fan are arranged sequentially from bottom to top. Physical isolation reduces oil splattering onto the fan blades. Multiple air guide holes are arranged on the air guide plate corresponding to the heating element, forcing airflow to pass through the air guide holes and over the heating element. Oil droplets evaporate or are intercepted at high temperatures, reducing adhesion. The airflow driven by the fan flows evenly through the air guide holes over the heating element, ensuring sufficient heat exchange before entering the cooking chamber through the air outlet of the heating chamber lower cover. This eliminates unheated airflow. The even arrangement of the air guide holes guides the airflow in a directional direction, forming a uniform heat field in conjunction with the directional design of the air outlet, improving the uniformity of food heating.

[0007] Furthermore, the orthographic projection outline of the air guide hole on the lower cover of the heating chamber coincides with the orthographic projection outline of the heating tube on the lower cover of the heating chamber, and the area of ​​the orthographic projection outline of the air guide hole on the lower cover of the heating chamber is less than or equal to the area of ​​the orthographic projection outline of the heating tube on the lower cover of the heating chamber.

[0008] By adopting the above solution, the air guide hole outline is completely aligned with the heating element and the projected area is limited, ensuring that the airflow can only pass through the area covered by the heating element, preventing the airflow from bypassing the heating element and directly entering the cooking cavity, so that the airflow is concentrated in the effective heating area of ​​the heating element, reducing the loss of heat in non-heating areas.

[0009] Furthermore, the center of all the air outlets is located on the vertical plane where the central axis of the heating element is located.

[0010] By adopting the above scheme, the vertical plane of the heating element's central axis is the central region for heat radiation and airflow convection. Concentrating the air outlets in this plane ensures that the airflow flows directionally along the core heating path of the heating element. The central axis plane of the heating element is also the main path for the rising of grease and steam. Concentrating the air outlets here forms an airflow barrier, guiding the grease towards the high-temperature area of ​​the heating element for evaporation or interception. Symmetrically distributed air outlets guide the airflow out smoothly, avoiding localized turbulence caused by outlet misalignment.

[0011] Furthermore, a heating chamber upper cover and an air guide seat are provided between the fan and the lower cover of the heating chamber. The heating chamber upper cover and the heating chamber lower cover are fastened together to form a heating chamber. The heating tube and the air guide plate are located inside the heating chamber.

[0012] By adopting the above solution, the upper and lower covers of the heating chamber are connected by a snap-fit ​​mechanism, which effectively disperses the stress generated by fan vibration. The snap-fit ​​connection, such as a clip, thread, or quick-release structure, forms an independent heating chamber module, integrating core components such as the heating element and air guide plate into the cavity. Workers only need to install the heating chamber module as a whole into the fan assembly, reducing the steps of debugging each component individually. The air guide seat is designed with a guide surface and a gradually narrowing air duct to rectify the airflow output by the fan and eliminate turbulence.

[0013] Furthermore, the upper cover of the heating chamber is provided with a first connecting channel facing the air guide seat, and the air guide seat is provided with a second connecting channel facing the upper cover of the heating chamber. The first connecting channel and the second connecting channel are sealed together, and the heat insulation plate is provided with clearance holes corresponding to the first connecting channel and / or the second connecting channel.

[0014] By adopting the above solution, through the sealed connection channel between the heating chamber cover and the air guide seat, combined with the precise fit of the heat insulation plate clearance hole, a comprehensive optimization of efficient airflow guidance, enhanced thermal isolation, simplified assembly, and improved durability is achieved.

[0015] Furthermore, a gap is left between the clearance hole and the first connection channel and / or the second connection channel.

[0016] By adopting the above solution, the reserved gap can form an air insulation layer, blocking the heat conduction path. If there is no gap between the clearance hole and the channel, thermal expansion may cause the component to jam or the structure to deform. The gap provides expansion margin and avoids stress concentration.

[0017] Furthermore, the lower cover of the heating chamber is provided with multiple connecting bosses, and the center of each connecting boss is provided with an arc-shaped groove that fits and conforms to the heating tube. A detachable clamping member is installed above the connecting boss to press the heating tube into the arc-shaped groove.

[0018] By adopting the above solution, the radius of the arc groove in the center of the connecting boss is strictly matched with the outer diameter of the heating tube, ensuring that the heating tube fits completely against the groove wall after being embedded. The clamping parts fix the heating tube by means of buckles, threads or magnetic attraction, which can improve the stability of the heating tube and make disassembly more convenient.

[0019] Furthermore, a support base is provided inside the lower cover of the heating chamber, and the support base is used to abut against the air guide plate.

[0020] By adopting the above solution, the support base can provide a certain support effect for the center of the air guide plate, and remain stable and undeformed under the continuous blowing of the fan.

[0021] Furthermore, the main component also includes a fixing frame, through which the heating component is mounted on the top of the heat insulation basket.

[0022] By adopting the above solution, the mounting bracket provides rigid support for the heating element, ensuring a tight fit between it and the top of the insulated basket. This prevents the element from shifting or falling off due to vibration or high temperature, thus improving the stability of the equipment. The heating element can be quickly and accurately installed at a preset position on the top of the insulated basket, ensuring that heat energy is evenly radiated into the cooking cavity, reducing heat loss and improving thermal efficiency.

[0023] Furthermore, the fixing frame has a hollow hole in the center, and the edge of the hollow hole has an annular flange for supporting the heating component.

[0024] By adopting the above solution, the edges of the heating element can be precisely wrapped, and the weight of the element can be distributed by replacing the traditional point support with surface contact.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By placing the fan on the top layer and using the lower components to form a physical barrier, splashing oil droplets are effectively intercepted, significantly reducing oil stains adhering to the fan blades, reducing cleaning frequency and maintenance costs. The air guide holes create an acceleration effect on the airflow, and the high-speed airflow can blow away the oil droplets. At the same time, the high-temperature environment makes it easier to vaporize, thereby reducing solid oil stains and extending service life. 2. The air vents are designed to correspond with the heating element, ensuring that airflow must pass through the surface of the heating element and completely enclose it for sufficient heat exchange before flowing into the cooking cavity through the vents. This completely prevents unheated airflow from entering, prolongs the contact time between the airflow and the heating element, and improves heat exchange efficiency. The cooking cavity heats up significantly faster, reducing energy consumption. The heat insulation plate is located between the air vent and the fan, reducing the cooling effect of the fan's cold air on the heating element, stabilizing the surface temperature of the heating element, and enhancing thermal stability. 3. The lower cover of the heating chamber acts as the first barrier, effectively blocking oil droplets and steam that splash during cooking, preventing them from directly contacting the upper heating element and fan blades, significantly reducing oil buildup on the internal heating element and fan, and reducing cleaning frequency and maintenance costs.

[0034] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0035] Please refer to Embodiment 1 of this utility model. Figures 1 to 5 As shown, an air fryer is provided, mainly including a main body component 1, a frying basket component 2, and a heating component 3. The main body component 1 includes an outer shell frame 11, a heat-insulating basket 12 installed inside the outer shell frame 11, and a fixing bracket 4. The outer shell frame 11 includes a side frame 111 and a base 112 fixedly connected. One side of the side frame 111 is open to provide an installation opening for the frying basket component 2. The fixing bracket 4 is fastened to the top opening of the heat-insulating basket 12 by screws. A hollow hole 41 is provided in the center of the fixing bracket 41, and the edge of the hollow hole 41 extends upward to form an annular flange for supporting and positioning the heating component 3 above. The frying basket component 2 is removably installed inside the heat-insulating basket 12, and its interior is a cooking cavity for holding food. In other embodiments, the fixing bracket 4 can be omitted, and the flange of the fixing bracket 4 can be directly and integrally installed on the top of the heat-insulating basket 12.

[0036] The heating element 3 is mounted on the top of the heat-insulating basket 12 via the annular flange 42 of the fixing frame 4. In some embodiments, the heating element 3 includes, from bottom to top, a lower cover 31 of the heating chamber, a heating tube 32, an air guide plate 33, a heat insulation plate 34, and a fan 37. The lower cover 31 of the heating chamber is fixed to the top of the fixing frame 4 or the heat-insulating basket 12 with screws to fix the heating element 3 as a whole. Multiple air outlets 311 are provided on the surface of the lower cover 31. These air outlets 311 are the only channels for the heated airflow to enter the cooking cavity of the lower frying basket. Preferably, the center point of all the air outlets 311 is precisely located on the vertical plane where the central axis of the upper heating tube 32 is located. This symmetrical and concentrated layout ensures that the hot airflow can be blown vertically downward along the most efficient path to form a uniform heat field, while forming an airflow barrier in the central area to effectively block rising oil stains. In other embodiments, some air outlets may not correspond to the heating tube 32 to achieve overall aesthetics of the air outlets.

[0037] The inner surface of the lower cover 31 of the heating chamber is also provided with multiple connecting bosses 312, and each connecting boss 312 has an arc-shaped groove 3121 machined in the center that matches the outer diameter of the heating tube 32. The heating tube 32 is placed in these arc-shaped grooves 3121. In this embodiment 1, the heating tube 32 is a serpentine spiral metal heating tube 32. In addition, a detachable clamping component 321, such as a buckle or a pressure plate, is provided, which is assembled above the connecting boss 312 to firmly press the heating tube 32 into the arc-shaped groove 3121. The clamping component 321 is fixed to the connecting boss 312 by fasteners such as bolts or screws. This ensures stable thermal contact and facilitates disassembly, replacement or cleaning in the future.

[0038] In some embodiments, the lower cover 31 of the heating chamber is further provided with at least one support seat 313 for supporting and positioning the air guide plate 33 from below, preventing it from vibrating or deforming under the action of airflow. Multiple support seats 313 are evenly distributed. Optionally, screw holes can be provided at the top of the support seat 313 for fixing the support seat 313 to the air guide plate 33 with screws or bolts. In this embodiment 1, the lower cover 31 of the heating chamber is provided with one support seat 313, located at the very center of the support seat 313.

[0039] It should be noted that the air guide plate 33 is laid flat above the heating element 32. Preferably, the air guide plate 33 is a metal plate or a high-temperature resistant engineering plastic plate with densely packed air guide holes 331. The arrangement of these air guide holes 331 is such that the orthographic projection outline of each air guide hole 331 on the lower cover 31 of the heating chamber completely coincides with the orthographic projection outline of the heating element 32 on the lower cover 31 of the heating chamber. Furthermore, the projected area of ​​a single air guide hole 331 is less than or equal to the projected area of ​​the corresponding segment of the heating element 32. This design forces all the cold air driven by the fan 37 to pass through the air guide holes 331 and flow closely through every segment of the heating element 32 for sufficient heat exchange, completely eliminating the possibility of airflow bypassing the heating element 32 and directly entering the cooking chamber, greatly improving thermal efficiency. At the same time, the dense holes have an accelerating effect on the airflow, which helps to disperse or vaporize rising oil droplets. In this embodiment 1, the air guide hole 331 is composed of strip and curved strip, and is arranged at intervals to form an enclosure, and the shape after enclosure is consistent with the heating tube 32.

[0040] In this embodiment 1, the heat insulation plate 34 is located above the air guide plate 33 and is made of high temperature resistant heat insulation material. Its main function is to block the upward transfer of heat, protect the fan 37 and plastic parts above from high temperature, and maintain the stability of the working temperature of the heating tube 32.

[0041] In this embodiment 1, a heating chamber cover 35 and an air guide seat 36 are also included between the heat insulation plate 34 and the fan 37. Therefore, the heating assembly 3 includes, from bottom to top, a heating chamber lower cover 31, a heating tube 32, an air guide plate 33, a heating chamber upper cover 35, a heat insulation plate 34, an air guide seat 36, and a fan 37. The heating chamber upper cover 35 and the heating chamber lower cover 31 are fastened together by a periphery snap-fit ​​structure to form a sealed heating chamber, encapsulating the heating tube 32 and the air guide plate 33 inside. The top center of the heating chamber upper cover 35 protrudes upward to form a first connecting channel 351. The air guide seat 36 is installed above the heating chamber upper cover 35, and its bottom is provided with a second connecting channel 361 that mates with the first connecting channel 351. The two are sealed by a sealing ring or interference fit to ensure the airtightness of the air passage and prevent air leakage. The air guide seat 36 is designed with a tapered air duct inside to rectify and accelerate the airflow. The heat insulation plate 34 has clearance holes 341 at positions corresponding to the first connecting channel 351 and the second connecting channel 361. The diameter of the clearance holes 341 is larger than the outer diameter of the channels, and a certain gap is maintained between them. This gap forms an air insulation layer, which further blocks heat conduction and provides the necessary space for the component to expand under heat, thus avoiding thermal stress damage.

[0042] The fan 37 is mounted on the topmost air guide seat 36, with its blades located at the air inlet of the air guide seat 36. During operation, the fan 37 draws in cold air from the top of the air fryer. The airflow passes sequentially through the air guide seat 36 (being rectified), the first and second connecting channels 361, and the air guide holes 331 of the air guide plate 33 (being accelerated and guided), evenly washing the surface of the heating tube 32 and being heated. Finally, it flows into the heating chamber and forms a high-speed hot air jet through the air outlet 311 on the lower cover 31 of the heating chamber, cooking the food in the frying basket.

[0043] During assembly, the heating element 32 is press-fitted onto the connecting boss 312 of the lower cover 31 of the heating chamber. The air guide plate 33 is then placed on top and positioned and fixed with the support base 313. Next, the upper cover 35 of the heating chamber is placed on top and fastened to the lower cover, forming an independent heating chamber module. Then, the heat insulation plate 34 is placed on the upper cover 35 of the heating chamber and connected to the fixing frame 4. Next, the air guide seat 36 is connected and sealed to the heating chamber module through the first connecting channel 351 and the second connecting channel 361. Finally, the fan 37 is installed on the air guide seat 36, and the entire integrated heating assembly 3 is installed onto the main frame via the fixing frame 4.

[0044] The working principle and beneficial effects of this utility model: 1. Prevention of oil contamination: During cooking, splattered oil droplets and steam are first physically blocked by the lower cover 31 of the heating chamber. Even if a small amount of oil mist rises, it will be intercepted by the air guide plate 33, or it will be instantly carbonized or evaporated because it must flow through the high-temperature heating tube 32, making it extremely difficult for it to continue rising to the fan blades 37 at the top. This keeps the fan 37 and the inside of the heating chamber clean, solving the cleaning problem and eliminating odors and safety hazards.

[0045] 2. High-efficiency heat exchange and uniform heating: The air guide holes 331 of the air guide plate 33 force the airflow to completely surround and flow through the heating tube 32, achieving sufficient heat exchange and ensuring that all airflow entering the cooking cavity is uniformly heated hot air. Combined with the symmetrically distributed air outlet holes 311 along the center surface of the lower cover 31 of the heating cavity, a uniform and stable heat flow field can be formed within the frying basket, ensuring consistent heating of food, better cooking results, faster heating, and greater energy efficiency.

[0046] 3. Modularity and Stability: The heating chamber is an independent module, facilitating production, assembly, and maintenance. The heating element 32 is fixed by the arc-shaped groove 3121 and the clamping member 321, ensuring a stable and reliable connection. The annular flange 42 of the fixing frame 4 provides surface support, guaranteeing the stability of the entire heating assembly 3 under operational vibration.

[0047] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
